We just keep picking up cute hair and makeup looks from Jennifer Lawrence on her Hunger Games promo tour. The lastest is this adorable, simple half-up 'do she wore on Late Night with David Letterman.

The sides of her hair were pinned back across the back of her head in overlapping layers. No barrette needed here, even—just a few hairpins. Just pull some hair back from the left side and pin. Then repeat on the right side. Then the left. Then the right again.

I was so pleased when I spotted this. The look is simple, which means it's easy to copy. And then it's cute to top it off. That's pretty much a dream come true for anyone with hair.
